Did you look at SteelSeries' display-toting Rival 700 mouse in January and think it was just the edge you needed for your gaming exploits? It's time to do something about it. The company's Rival 700 is now available for a pricey (though not outlandish) $100. As before, its centerpiece is a side-mounted OLED screen that both shows data (such as your in-game stats or your team logo) and helps you tweak settings without firing up software on your PC. You can also 'feel' events through customizable vibrations, and swap optical sensors when you're eager for an upgrade. Is this overkill? Probably -- but there's no doubt that you'll have a distinct gaming experience.
